EKI-2526M - 4 Port 10/100BaseTX + 2 Port 100BaseFX Multi-mode Fibre Unmanaged Industrial Ethernet Switch


CE is a mandatory standard for products on the market in the European Economic Area. By CE marking a product, the manufacturer ensures that the item meets the essential safety requirements set out in the applicable CE directive.


This product fully adheres to the Restriction of Hazardous Substances Directive 2002/95/EC, RoHS for short.  The directive covers the restriction of use of certain hazardous substances in electrical and electronic equipment and was adopted in February 2003 by the European Union.


Underwriters Laboratories (UL) is an independent product safety certification organisation based in the United States. UL develops standards for products, materials, components, assemblies, tool and equipment, mainly dealing with product safety.

Class 1 Division 2 Certified

The National Electrical Code (NEC) defines hazardous environments as areas “where fire or explosion hazards may exist due to flammable gases, vapours, liquids, dust or particles”. When such materials are found in the atmosphere of an area, a potential for explosion exists, which could be ignited if an electrical or other source of ignition is present. As defined by the classification authorities, certified devices are suitable for installation and operation within a Class 1, Division 2 environment. Class 1 environments are areas where there is a presence of flammable gases or vapours in the air, such as natural gas or petroleum vapour. Facilities including oil rigs, refineries, gas plants and automotive repair centres all fall within this category.

Wide Voltage

These devices and systems have been designed to accept a wide voltage DC power input. This feature is desirable in the industrial market where a fixed voltage level or mains AC power cannot be guaranteed.

FCC Approved

The Federal Communications Commission (FCC) is an independent agency of the United States government that sets standards and governs the testing of conducted and radiated emissions such as EMI.

5 Year Warranty

These products come with a standard five year manufacturer warranty.

The EKI-2526M is a four port copper and two port multi-mode SC or ST fibre unmanaged Ethernet switch from Advantech. Protected by a high quality IP30 rated metal enclosure, the EKI-2526M is ideal for industrial networking applications.

In true industrial style, the EKI-2526M can operate in a variable -10°C to +60°C temperature range and can accept a wide 12V to 48V DC power input. For added stability, the EKI-2526M features two power inputs that fails over when main power source is interrupted or lost.

The EKI-2526M is available to purchase directly from Impulse. For more information about the EKI-2525M, please contact our technical sales team on +44 (0)1782 337 800, or alternatively submit an enquiry.
